fat in tissue

Explanation:

Biomolecules like carbohydrates, fats etc. are well known for their energy storing abilities. Glucose, as a carbohydrate, is the most used source of energy but is stored in excess as glycogen in the muscle and liver cells.

However, fats are far more efficient in storing energy than carbohydrates or proteins because they give more ATP per molecule. Fats are stored in tissues of the body called ADIPOSE tissues. Hence, the richest source of stored chemical energy in the body is FATS IN TISSUES.
